San Bernardino shooting: Who are the victims?
Authorities have named the 14 victims of the attack on a social services centre in San Bernardino, California. Twenty-one more people were injured.
Mostly county employees, a group of people gathered on Wednesday for a holiday party with no indication of what was to come from their co-worker Syed Rizwan Farook.
Survivors expressed shock that Farook, a quiet employee of the county for years, could orchestrate such an attack.
Bomb equipment, weapons and thousands of rounds of ammunition were found by police in a raid after a shootout that killed the two suspects.
Authorities still have not found a motive in the attack by Farook, 28, and his wife or fiance Tashfeen Malik, 27.
However, US officials have told the media Tashfeen Malik pledged allegiance to the leader of the Islamic State (IS) group on Facebook.
Here are the victims and their stories.
